<h2>Description</h2>
<p>
Receives an arate signal into an instrument through a named port.
</p>
</div>
<div class="refsect1">
<a id="idm281472923471336"></a>
<h2>Syntax</h2>
<pre class="synopsis">asignal <span class="command"><strong>inleta </strong></span>Sname</pre>
</div>
<div class="refsect1">
<a id="idm281472923469128"></a>
<h2>Initialization</h2>
<p>
<span class="emphasis"><em>Sname</em></span> -- String name of the inlet port.
The name of the inlet is implicitly qualified by the instrument name
or number, so it is valid to use the same inlet name in more than one
instrument (but not to use the same inlet name twice in one instrument).
</p>
</div>
<div class="refsect1">
<a id="idm281472923467240"></a>
<h2>Performance</h2>
<p>
<span class="emphasis"><em>asignal</em></span> -- audio input signal
</p>
<p>
During performance, the arate inlet signal is received from each instance of an instrument
containing an outlet port to which this inlet has been connected using the <a class="link" href="connect.html" title="connect">connect</a> opcode.
The signals of all the outlets connected to an inlet are summed in the inlet.
</p>

<h2>Examples</h2>
<p>
Here is an example of the inleta opcode. It uses the file <a class="ulink" href="examples/inleta.csd" target="_top"><em class="citetitle">inleta.csd</em></a>.
